Hardware 3d acceleration is enabled and works fine with glxgears but when I
start a 3d sofware like google-earth it falls back into sofware rendering with
the following error:
*********************************WARN_ONCE*********************************
File r300_render.c function r300Fallback line 486
Software fallback:ctx->Line.SmoothFlag

My system is a P4 3,0 Ghz 1,5Gb RAM with ATI RADEON 9800SE video card

By commenting out you have accelerated line drawing but not smooth line drawing
even though with hight screen resolution and small linewidth you probably won't
see the difference.
Anyway the message you see doesn't mean it fallback fully in software rendering
just that smooth line are drawed using software. So please don't report bug for
that. This are functionality not yet implemented.

The current situation is that unpatched Mesa r300 provides horrible performance
for an important application. Until the functionality is implemented, perhaps
there should be a runtime config option to ignore the flag instead of falling
back to software rendering?
